César himself is the behind the scenes type. And it occurs to him, then, as he's listening, that this is... similar to how he barely escaped with his life at Abysus. Except he had no one but himself to recover from that emotionally. In fact, he buried it. Her experience sounds worse, though. More visceral.

For a moment, that realization shows on his face, a quiet sort of eyes widening before his expression shifts back to what it was, concern for her. Buried again, if only to talk to someone else (a husband?) another time.

"Johnny's good at getting things out of people. And I'm glad Erin's helping, too. What a terrible man. I'm... glad he's dead." César hesitates, because he's still a pacifist, but sometimes, well, even he can't help himself.
